Findings and Conclusions ......................................................................... 24 i A. Introduction 1. Purpose of the Addendum to (EAR). This Addendum to the Environmental Assessment Report (EAR) was prepared based on a Chinese version of the Feasibility Study Report (FSR) and Environmental Assessment Table which was approved by Huanggang EPB in 2018 for the new proposed subprojects under Hubei Huanggang Urban Environment Improvement Project (the Project). The Addendum is to be submitted to ADB for review and approval. 2. The project. The Project is the first key urban environmental initiative of the Huanggang Municipality Government (HMG) with nationwide demonstration potential. The project design incorporates lessons from (i) Yi’ai Lake rehabilitation–a recent locally funded initiative, and (ii) other ADB supported lake and river restoration projects in the PRC. The project design was optimized based on best international practices: (i) the need to take an integrated approach to water system rehabilitation, and (ii) the importance of using simulation techniques to predict likely outcomes. The project will also complement the past and ongoing projects which are contributing to reducing pollution in the Yangtze River. Since the drinking water intakes of several cities are downstream from the Yangtze River, the project also contributes to protection of vital drinking water source. 3. Changes have been made to the project scope during the project implementation. During the ADB Inception Mission in November 2015, the PMO proposed the change of sediment dredging method from cutter suction dredging to drain and pump and the sediment treatment method from dewatering and solidification to vacuum pre-compaction. The PMO submitted the Due Diligence Report for Environment of Chiye Lake subcomponent in July 2016. During the ADB Review Mission in August 2016, other 8 changes were proposed by PMO according to the designs. The first Addendum to the EAR was prepared and submitted to ADB in June 2017 and revised according to ADB’s comments. In March 2018, PMO proposed another six changes for the midterm adjustment. Study Report (FSR) and the domestic Environmental Assessment Table completed have been completed in 2018. Please see chapter B for the detailed information of the changes. 4. Environmental Assessment for the Project. An Environmental Assessment Report (EAR) was prepared in accordance with the requirements of the Asian Development Bank (ADB) Safeguard Policy Statement (SPS 2009) on the basis of the domestic EIA report that meets the requirements of the People’s Republic of China (PRC) EIA Law (2003) and associated regulations. The EAR was prepared based on two domestic Environmental Impact Reports (EIR) prepared for this project: a planning EIR, and a construction project EIR; and supplemented with information from the domestic Feasibility Study Report (FSR) and the Soil Erosion Prevention Plan (SEPP) for the project. 5. This project is classified as Category A for environment on the basis of ADB’s Rapid Environmental Assessment (REA), requiring the submission of a comprehensive environmental impact assessment (EIA) report. 6. Bases of the second Addendum to the CIEE preparation. This Addendum is prepared primarily based on the information collected from the FSR, Environmental Assessment Table prepared for the new proposed Subprojects. The Addendum was prepared in accordance with both PRC environmental laws/regulations and ADB’s environmental policies. The Addendum preparation also followed both PRC and ADB guidelines on environmental assessment. 2 B. Description and Rationales of Proposed Changes 7. Newly proposed components are located within urban area of Huanggang city, including six subcomponents including Diversion Canal and Culvert Gate of Nanhu pumping station, Wuqi Channle, Sugong River, the East Extension of Qingshui River, the Connection of Dongchang River and Dongtai River and Chiyehu Road. According to the Resettlement Due Diligent Report for the new subprojects, total area of state-owned land occupation will be about 386.6 mu, and 54 households, 205 persons will be affected, while the total area of collective land acquisition will be 13.8 mu, 15 households, 53 persons will be affected. The temporary land occupation will be state-owned with an area of 8.5 mu and there will be no resettlement. Mainly proposed construction contents are illustrated in Table 1.

A comprehensive analysis of the feasibilities of the six engineering subprojects has been undertaken. The technical designs are suitable for local circumstances, topography, and climate (arid desert conditions with long, harsh winters), consistent with strategic and sector priorities, and PRC design guidelines and local regulations. For the more detailed information of the subproject technical designs and analysis, please see report of Technical Feasibility and Sector Analysis of Subprojects which would be submitted to ADB in 2018.
